ENVELOPE. I r

Application i11ed"May 13,

Z '0 all whom it may concern:

. Be it known that I, Cnn rono Onno STEMEN, a citizen of the United States, and a resident of Detroit, in thecounty of Wayne and State'of Michigan, have invented certain new and useful Improvements in Envelopes, of which the following is a specification. i

This invention relates to envelopes and more particularly to one of that type adaptedfor use where a reply is anticipated or for; commercial use where an envelope is placed inside of another envelope for a 1'e-' ply, the present device serving to obviate the necessity of employing or having on hand two difi'erent sizes of envelopes and permittingpne to take the place of the two, thus resulting'in a great saving in paper in addition to the cost of envelopes since envelopes constructed i i-accordance with the present" invention requires less paper than.

two ordinary envelopes and can be pin [chased considerably cheaper, while it may also be used for advertising purposes, mail matter" being placed inside i and both flaps folded and mailed for one-cent postage.

Furthermore, there will be no mistakes in the returnaddress as it is always plain on 1 v the envelope or printed thereon by the'party or firm using the same. I a

The invention also contemplates the profvisi'on of'an envelope embodying 'a novel f arrangement of body andljflap portions adapted'to be foldedin a'novel'way to constitute sending and return envelopes, the parts being so arranged that all of: the flaps which areprovided with mucilage or other adhesive'm'ater ial are disposed on one-side.

and theparts to beprinted'on-the other side,

' wherein this constitutingan important factor in the manufacture inasmuch as it saves two .OPQI? ations over the old time envelope lwherelpart of the mu'cilaged surface'was on oneside and part on the other, and the same with,

the printing.

Other and further objects of my invention will become readily apparent to persons skilled in'the art, from-a consideration of the following description when takenin connection with Figure 1 is a perspective view of the improved envelope folded when used as an I {original sendingenve'lope.

Referring to the drawings in detail in which like reference characters designate corresponding parts throughout the several views, my lmproved envelope comprises a front portlon 10 contiguous with thebottom i edge ofthe back portion 11, bothbeing of vertical sectional view of' equal size, and formed 'of paper for other suitable material common in the art. At

one end of the back portion 11 is provided 1 an auxiliary front portion-12 corresponding- I back portions '10 and 11.- The back portion llisprefer'ably cut out or recessed in concaved "forrnationyas indicated at13 and a line 14-18 providedbetween the front and backporti ons .10 and llfin order that the front portion 10 may besevered'or detached 1 perforated or scored alongsai'd line for a purpose to be hereinafter explained. The front portion 1() is fur- I the-r provided with aflap "15 provided with i an adhesive or mucilaged surface 16 along the tapered edge portionthereof; said-flap being designed to befolded on-the line .17 I

and having in addition,flspace'd from-said line' and parallel thereto .or sloping from the center to said line at the ends ofthe front portion, 10 a scored line 18 intermedie ately of which is disposed asmall andprefhole or; aperturev 19 adapted for the insertionnf,a-pencilor the like or an envelope'opener, in order thatsthe flap 15 may be severed along said dotted,-scored or perforated line 18-:to 'permitopening of the envelope, after the same has beenffolded.

and forwarde'dEas will be later described. "The auxiliary front portion l2is provided at T the top-edge contiguous'withthe' edge of the back portion 11 having the recess 13 with a I sealing or closingflap 20 ,the" mucilaged or adhesivesurface 21 of which is disposed at the same 'sidefas the mucilaged surface 16 of the sealing or closing flap '15,

It'will' also be observed that the flap 20 ex tends .in the opposite direction from the di',

rection ,of extent of the flap 15 when the blank is opened out, ,in-the manner shownin Figure 20f thedrawings; At the opposite tion 12 is provided'a narrow projecting flap 22' having a niucilaged or adhesive surface 23 on the same slde ofthe blank correspond- 111g with'the sides-vat which; the coatings 16 a and 21 of the tapered H -g or closingflaps o in connection with the scored or perforated line, greatly facilitates opening of the envelope by inserting a lead penciljor other cessity of having two sizes of envelopes. In

addition, the flaps 15, and 20 maybe simultaneously folded into the envelopes and the envelope then mailed for one cent postage, both flaps arranged in this manner serving to stiffen the envelope so that accidental opening or displacement is avoided. In addition, there will also be no mistake in the return address as it is always plain on the envelope or printed thereon by the party or firm using the same.

In view of the foregoing it is thought that implement and lessening the danger of damthe operation of the device will be readily understood and in view of the simplicity and i practical value, that it will readilycommend itself to those skilled in the art.

Having thus particularly described and ascertaiud the nature of the invention, what An envelope having a front portion and a back portion and having a perforatedline constituting the line of fold between said portions, an auxiliary front portion connected with the back portion and disposd between,

the front and back portion, said auxiliary front portion having a flap 'cooperable with the back portion, said front portion also back portion andhavin'ga perforated line a bove the afli'xed part thereof and furth erhaving an opening located. on said last mentioned perforated line and adapted ,to admit of the insertion of an instrument for tearing the flap forated line.
